Tunnels can be classified according to different standards, such as purpose, geological conditions, buried depth, location, etc. The main functions of tunnels include transportation, water conservancy, municipal administration, mining, etc. Tunnels can be used for three-dimensional transportation, crossing mountains and ridges, underground passages, crossing rivers and seas, pipeline transportation, underground cables, water conservancy projects, etc. Tunnels can be underground passages or located underground. The latter are usually called underground tunnels. In addition, tunnels can also be divided into different types according to the size of their cross-sectional areas, such as very small section tunnels, small section tunnels, medium section tunnels, large section tunnels and extra-large section tunnels. In tunnel construction, in order to ensure the firmness and reliability of the tunnel, it is often necessary to tie steel bars on the inner wall surface of the tunnel and use concrete for pouring. In the prior art, the steel bars can only be tied on site with the help of a steel mesh trolley, and the steel bars are tied one by one manually on site; the construction time is long and the efficiency is low; the construction quality is poor, the shape and position of the steel mesh cannot be guaranteed, and the thickness of the concrete protective layer cannot be ensured; there are many construction workers on site, and there are great safety hazards; the prior art lacks a steel mesh that can be installed in pieces. Therefore, how to provide a tunnel secondary lining steel mesh and arch frame installation all-in-one machine is a problem that technicians in this field urgently need to solve.
